maybe the heat source is actually from thigh friction.. hmmm

It also has an innovative AIO hybrid cooling system that uses both air, and blood, to keep the outer chassis cool.

Pretty cool to think that I could... make my bicycle ride marginally easier by carrying a propane torch with me and blowing fire between my legs?

Makes me wonder where you draw the line between a powerful e-bike and a low power motorcycle.

Personally, if it's capable of slow highway speeds (45 and up), has more than 30 miles of range, and full safety lighting, then it's a low power motorcycle. Anything less is a bike.

Legally speaking though, it's actually pretty diverse by area. For instance, California requires pedal assist integration, eg if it can accelerate with no pedal movement it's a motorcycle, and then the bikes have 3 levels of classification (why though? Not sure), with max output regulated to 1600W (afaik since I don't live there). In other places they're more lax with regulation, just depends.

That's usually legally defined somewhere depending on your location. Wher I am it's defined based on rated power output of the motor.

Probably at the MoPed

It ain't a motorcycle if the engine isn't bigger than 50 cc, taps head.

[-] tunetardis@lemmy.ca 3 points 1 week ago

Ok I think I understand. You need something more than an easy level Mario Kart.

[-] SolacefromSilence@fedia.io 1 points 1 week ago

Kind of, in some states it's regulated like that, but in others it's not addressed at all. I had a joke in my reply, where it's true in my state that you need a motorcycle license for anything larger that 50 cc, but cc aka cubic centimeters of air displacement is a measure of Internal Combustion Engine size and has no correlation with electric vehicles. My state needs to update the regs and deal with e bikes going 25-30 mph down bike paths.

I feel like having the horsepower of an entry level motorcycle is a decent benchmark.

[-] SirActionSack@aussie.zone 5 points 1 week ago

Torque should also be part of it. Plenty of 250W e bikes that make 80+ Nm.

That's similar torque to a 750 - 800cc motorbike.

[-] Saleh@feddit.org 4 points 1 week ago

An e-bike might only weight 25 kg where a low powered motorcycle is at more than 100 kg.

More power by weight is faster and can be more dangerous

[-] InternetCitizen2@lemmy.world 5 points 1 week ago

Good point. Maybe similar HP/mass ratios? Idk

Great work by Tom Stanton here, thanks

I saw the video, and I have to say it was amazing!
